Tweeter is the name of a speaker driver, an audio retail chain, and a Warner Brothers cartoon character. No, wait, that would be Tweety Bird. However whimsical the name may sound, the tweeter plays a crucial role in speaker design. An average one delivers not only high frequencies, as the chirpy name suggests, but also a significant share of the upper midrange. It's possible to design a loudspeaker without a tweeter. But most speakers depend on their tweeters to deliver harmonics, detail, airiness, and all frequencies above the crossover to the lower drivers.

Although they're now owned by Klipsch, Mirage continues to follow their own ears. The Toronto-based company's name derives from a key design goal—to make speakers so immersive that the listener forgets the product is in the room.

So here I sit, my furniture all rearranged like an overcrowded antique store, just so I can be in the sweet spot. It is speaker review time again at the Manteghians.' It takes a long time to break out and set up speakers, and you've lots of boxes to deal with. But the simplicity of a speaker is what is most appealing. No HDMI to DVI handshaking problems, no video cross-coding issues, no 3:2 pulldown. You just sit down and listen to music and watch movies. Of course, it's only enjoyable when the speakers in question sound great – like this Definitive Technology Mythos system does.
